Problems solved by technology

[0002] In the existing middle school textbooks, one large beaker and two small beakers are used to do the gas molecule (ammonia) movement experiment, and another large beaker is used to demonstrate the diffusion of magenta in aqueous solution. The two experiments require two sets of equipment for Experiments demonstrating molecular motion consume a lot of experimental reagents, and the concentration of ammonia in the classroom during and after the demonstration is too high, which affects the teaching environment and the physical and mental health of students and teachers

Embodiment

[0033] see figure 1 — image 3 , the demonstrator is a closed transparent rectangular box body, the middle part of the box body is provided with an up and down pull-out partition 1 to divide the box body into left and right chambers that are not connected to each other, the left side of the box body 1. The opening on the right side is respectively provided with a first plug 2 made of a rubber plug which acts as a seal, and the inner side of the top wall of each chamber is provided with a suspension assembly along its length direction, and each suspension assembly consists of a pipe body 31. Two hanging lugs 32 are formed. The two hanging lugs 32 are parallel to each other and arranged at intervals along the length direction of the corresponding chamber. The lower part of the hanging lugs 32 is provided with a notch 33 that matches the tube body 31. The center of each notch 33 The connection direction of the wire is consistent with the length direction of the corresponding cha...

Abstract

The invention relates to a multifunctional minitype molecular motion demonstration instrument which is a sealed transparent box body, wherein a drawing partition plate is arranged in the middle of the box body so that the box body is divided into a left cavity and a right cavity which are not communicated with each other; openings at left and right sides of the box body are respectively provided with a first choke plug which plays a role in sealing, and a suspension component is arranged at the inner side of the top wall of each cavity in a length direction; and a plurality of pieces of linearly-arranged test paper are hung on each suspension component, and a chemical solution dripping hole is formed on the top wall of each cavity and is sealed through a second choke plug. A gas molecular motion experiment and a liquid particle motion experiment can be conveniently and rapidly demonstrated in the demonstration instrument, and the two experiments are not influenced by each other. The demonstration instrument has the advantages of good demonstration effect, low experiment reagent dose and excellent promotional value.
